I have to say that it is a terrible scanner. Squelch has no hysteres and hack like a machine gun if the signal are weak. It overloads as soon as you connect a bigger antenna. The overload issue comes from that it is too sensitive. So if used where there are no risk to overload it can receive very weak signals. It has IC-V communication so can be computer programmed and controlled from a Scout type of frequency counter device. I would say it's worth £50, that's what I paid for mine.
